Banana Bread Brownie Bars – The Perfect Fusion of Moist Banana Bread and Fudgy Brownies

Why You’ll Love This Recipe

These bars are the best of both worlds: the homey flavor of banana bread meets the texture of a brownie. They’re moist but not overly dense, rich without being too sweet, and full of layers of flavor from banana, chocolate, and vanilla. The batter comes together in minutes, using simple pantry ingredients, and bakes into a beautifully golden, fragrant tray of comfort. Whether you serve them plain, dusted with powdered sugar, or topped with a chocolate drizzle, they’re an instant hit.

Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Ripe Bananas: The foundation of flavor — the riper, the sweeter and more aromatic.

Unsalted Butter: Adds richness and creates a tender, moist crumb.

Brown Sugar: Deepens the flavor with subtle caramel notes.

Granulated Sugar: Balances the sweetness and helps create a soft texture.

Eggs: Provide structure and keep the bars moist and chewy.

Vanilla Extract: Enhances both the banana and chocolate flavors.

All-Purpose Flour: Gives the bars structure without making them heavy.

Baking Powder: Helps the bars rise slightly while keeping them dense and brownie-like.

Salt: Balances sweetness and enhances overall flavor.

Cocoa Powder: Provides that deep, chocolatey contrast to the banana layer.

Chocolate Chips (optional): For extra gooey richness throughout.

Chopped Walnuts or Pecans (optional): Add crunch and a nutty flavor that pairs beautifully with banana and chocolate.

Directions

Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper and lightly grease it.

In a large bowl, mash the ripe bananas until smooth. Add melted butter, brown sugar, granulated sugar, eggs, and vanilla extract. Whisk until well combined.

In a separate bowl, whisk together flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture until just combined — do not overmix.

Divide the batter in half. To one half, add cocoa powder and mix until fully incorporated.

Spread half of the banana batter (without cocoa) into the prepared pan. Spoon the chocolate batter on top in dollops, then add the remaining banana batter. Use a knife or skewer to gently swirl the layers together for a marbled effect.

Sprinkle chocolate chips or nuts on top if desired.

Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Cool completely in the pan before slicing into bars.
